    Your second block of code looks better. But, starting a Task and then immediately waiting on it is pointless. Just call Take and then process the item that is returned directly on the consuming thread. That is how the producer-consumer pattern is meant to be done. If you think the processing of work items is intensive enough to warrant more consumers then by all means start more consumers. BlockingCollection is safe multiple producers and multiple consumers.

    public class YourCode
{
  private BlockingCollection queue = new BlockingCollection();

  public YourCode()
  {
    var thread = new Thread(StartConsuming);
    thread.IsBackground = true;
    thread.Start();
  }

  public void Produce(object item)
  {
    queue.Add(item);
  }

  private void StartConsuming()
  {
    while (true)
    {
      object item = queue.Take();
      // Add your code to process the item here.
      // Do not start another task or thread. 
    }
  }
}
